Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, the accompanying drawing that the following describes is only some embodiments recorded in the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the perspective exploded view that front folding of the present invention prevents turning over a detailed description of the invention of type electric wheelchair;
Fig. 2 is that front folding of the present invention prevents the view after turning over type electric wheelchair folds.
Detailed description of the invention
Below in conjunction with each embodiment shown in the drawings, the present invention is described in detail; but should be noted that; these embodiments are not limitation of the present invention; those of ordinary skill in the art are according to these embodiment institute work energy, method or structural equivalent transformations or substitute, and all belong within protection scope of the present invention.
As shown in Figure 1, front folding of the present invention prevents that turning over type electric wheelchair 100 comprises: wheelchair frame, armrest system, latch assembly, storage bag and anti-translation frame 50.
Described anti-translation frame 50 is for placing translating into of electric wheelchair, and it specifically comprises anti-translation frame body 51 and is arranged at the auxiliary wheel 52 of described anti-translation frame body both sides.Wherein, before described anti-translation frame body 51, pan and described lower backrest 12 times pans are connected, and form the first linkage structure.The auxiliary wheel 52 of described both sides when electric wheelchair runs, can with earth surface, the operation of auxiliary electrical wheelchair.Meanwhile, auxiliary wheel 52 increases the contact area on electric wheelchair and ground, and what electric wheelchair was run is more stable.
As shown in Figure 2, in addition, during described electric wheelchair folding, described anti-translation frame 50 has folding direction forward.Setting like this, after electric wheelchair folding, anti-translation frame 50 can not be opened automatically, thus has better safety.
Described wheelchair frame forms the agent structure that front folding prevents turning over type electric wheelchair.Described wheelchair frame comprises: upper backrest 11, lower backrest 12, seat frame frame 13, front frame 14 and Rear frame 15.
Wherein, described upper backrest 11 and described lower backrest 12 chain connection, described lower backrest 12 upper hinge hole is connected with pan after seat frame frame 13, in described lower backrest 12, pan is connected with pan after described Rear frame 15, lower backrest 12 times pans are connected with pan after described Rear frame 15, before described Rear frame 15, pan is connected with the front pan of described seat frame frame 13, and described front frame 14 upper hinge hole is connected with pan before described Rear frame 15.Thus the Rear frame 15 in described wheelchair frame, seat frame frame 13 and lower backrest 12 form the second linkage structure.In addition, described storage bag 40 is arranged at below described seat frame frame 13, and it extends the using function of electric wheelchair effectively, is convenient to user and carries self article, make full use of the space below seat frame frame 13.
Further, when front folding of the present invention prevents turning over the folding of type electric wheelchair, upper backrest 11 can pan be that hinge point carries out relative rotation with lower backrest 12, and final folding is got up.In addition, the buckle seat 82 that described upper backrest 11 and lower backrest 12 are respectively arranged with buckle 81 and can match with described buckle 81, thus, when described electric wheelchair is in folded state or deployed condition, described front folding can be prevented turning over type electric wheelchair locks, and opens or auto-folder automatically to prevent electric wheelchair by described buckle 81 with coordinating of buckle seat 82.Meanwhile, after folding, in order to opening of auxiliary electrical wheelchair, described front folding prevents that turning over type electric wheelchair 100 also comprises air spring 60.
In addition, because anti-translation frame 50 has folding direction forward, even if buckle 81 not locking, anti-translation frame 50 also can not be opened, thus safety is better.
Described front folding prevents that turning over type electric wheelchair 100 also comprises damping spring 83, and described damping spring 83 is arranged between described upper backrest 11 and lower backrest 12.Thus when electric wheelchair launches, the active force on damping spring 83 available buffer between backrest 11 and lower backrest 12, both protected electric wheelchair, added comfort level when user uses simultaneously.In addition, described front folding prevents that turning over type electric wheelchair also comprises seat back cushion, and described seat back cushion is installed on described seat frame frame 13 and upper backrest 11.
Described front folding prevents that turning over type electric wheelchair 100 also comprises: battery 71, battery case 72 and battery carrier 73.This battery 71 is the power that front folding prevents turning over the operation of type electric wheelchair, described battery 71 and battery case 72 are fixed in described battery carrier 73, described battery carrier 73 is positioned at below described seat frame frame 13, and pan and described front frame 14 times pans are connected before described battery carrier, after described battery carrier 73, pan is connected with described lower backrest 12 upper hinge hole.Thus, described front frame 14, Rear frame 15, lower backrest 12, battery carrier, formation quadric chain.
In addition, described air spring 60 upper hinge hole is connected with pan after described battery carrier 73, described air spring 60 times pans are connected with pan after described anti-translation frame 50, thus described lower backrest 12, anti-translation frame 50, air spring 60, battery carrier 73 form the 3rd linkage structure.Described first linkage structure, the second linkage structure, quadric chain and the 3rd linkage structure can form interlock in electric wheelchair folding or when opening, to facilitate the Quick folding that realizes electric wheelchair and to open.
Described armrest system comprises handrail tube 21, handrail tray 22 and handrail stay tube 23.Wherein, described handrail tray 22 respectively with described handrail tube 21 and handrail stay tube 23 chain connection, described handrail tube 21 and handrail stay tube 23 simultaneously respectively with described upper backrest 11 and seat frame frame 13 chain connection.Thus armrest system also can carry out folding.
Further, described front folding prevents that turning over type electric wheelchair 100 also comprises: front-wheel 91, trailing wheel 92 and motor 93, wherein, described front-wheel 91 realizes the connection with described front frame 14 by front fork 94, described trailing wheel 92 is connected with described Rear frame 15, and described motor 93 provides driving force for described trailing wheel 92.Described trailing wheel 92 is as driving wheel, and the diameter of trailing wheel 92 is greater than front-wheel 91 simultaneously.In addition, described front folding prevents that turning over type electric wheelchair 100 also comprises mud guard 95, and described mud guard 95 is positioned at the top of described trailing wheel 92, and is connected with described lower backrest 12.Described motor 93 is electrically connected with battery 71 simultaneously, and described battery 71 provides the electric energy of running for described motor 93.
Described front folding prevents that turning over type electric wheelchair 100 also comprises foot rest 96, and this foot rest 96 is for supporting the foot of user, so that user is had a rest.
In sum, anti-to turn over the safety of type electric wheelchair good, easy to use for front folding of the present invention.It is arranged anti-translation frame be effectively prevent translating into of electric wheelchair by this, and anti-translation frame can be folded to form interlock with electric wheelchair, is convenient to folding and the use of electric wheelchair.In addition, front folding of the present invention prevents that turning over type electric wheelchair also has storage bag, extends the using function of electric wheelchair effectively.
